Nutritionix. Nutritional Info: Nuts, acorns, raw. Fats and Fatty Acids The chart below shows good fats in Nuts, acorns, raw in relation to bad fats. Read more about each type of fat and fatty acid below. Polyunsaturated Fats: Polyunsaturated fat can be found mostly in nuts, seeds, fish, algae, leafy greens, and krill.

Whole food sources are always best, as processing and heating may damage polyunsaturated fats. Monounsaturated Fats: Foods containing monounsaturated fats reduce LDL (bad) cholesterol, while possibly increasing HDL (good) cholesterol. Trans Fatty Acids: The National Academy of Sciences has concluded there is no safe level of trans fat consumption. Saturated Fats: Consumption of saturated fat is a risk factor for cardiovascular disease in the view of the Canadian Heart and Stroke Foundation, the American Heart Association, the British Heart Foundation, the National Heart Foundation of Australia, the National Heart Foundation of New Zealand and the World Heart Federation.

Nutrition Facts and Analysis for Snacks, beef jerky, chopped and formed. Naming Carboxylic Acids : Names of Carboxylic Acid Compounds : Organic Chemistry. (Chemical) Definition of Carboxylic Acids: Names of Carboxylic Acids in General Carboxylic Acids are named according to the same system as other organic compounds, with the suffix -oic acid used to indicate that both a carbonyl group and a hydroxyl group are both attached to the same carbon atom, which is located at the end of a chain or branch of carbon atoms forming the molecule (except in the case of methanoic acid, which includes only one carbon atom).

The first step to consider when working out the name of a carboxylic acid molecule is the number of carbon atoms forming a chain. If they are attached together in a linear (i.e. unbranched) configuration then the number of carbon atoms is indicated according to the same system as used for naming alkanes. The simplest linear caboxylic acids are named and their structures drawn in the following table. Names and Structures of simple Linear Carboxylic Acids. N09_WhatAreTheTypesOfFat.pdf.

How Fat Cells Work" ­A little more than half of the adults in the United States are overweight. Statistics show that an incredible 65.2 percent of the U.S. population is considered to be "overweight" or "obese. " According to the Centers for Disease Control and Prevention (CDC), obesity and overweight status is determined in adults by finding a person's "Body Mass Index" or BMI. BMI is a calculation that takes into consideration both a person's body weight and height to determine whether they are underweight, overweight or at a healthy weight. An adult who is considered "overweight" has a BMI somewhere between 25 and 29.9.

An adult with a BMI of at least 30 is considered "obese. " This measurement is used because it's typically a good indicator of body fat. Whether due to concern for related health risks (high blood pressure, heart disease, diabetes, sleep apnea, respiratory problems, etc.), or just for sheer aesthetics, many Americans worry about fat.

Hands-on Activities for Teaching Biology to High School or Middle School Students. By Drs. Ingrid Waldron and Jennifer Doherty, University of Pennsylvania The expression "hands-on, minds-on" summarizes the philosophy we have incorporated in these activities - namely, that students will learn best if they are actively engaged and if their activities are closely linked to understanding important biological concepts.

Some of our activities are explicitly aligned with the Next Generation Science Standards, as indicated by (NGSS) in the descriptions below and the links to the right. Additional information is provided in Summary Tables and in the Teacher Preparation Notes for these activities. In the months to come we will publish additional activities that are aligned with the Next Generation Science Standards. We encourage you to subscribe to our listserv to receive notices when we post new activities or significantly improved versions of current activities.

Chocolate Milk Improves Recovery and Athletic Performance? Posted on Competitive athletes need to recover quickly from bouts of training as well as competition to prepare for subsequent events. Studies have shown that post-exercise consumption of carbohydrates and protein results in better recovery than consumption of carbohydrates alone. Post-exercise supplementation is important both for restoring muscle glycogen levels and also for attenuating muscle damage for better recovery. Does post-exercise protein/carbohydrate consumption help… One question, however, for athletes is whether or not consumption of protein and carbohydrates after exercise actually results in improvements in athletic performance. In this study, the authors compared supplementation in the form of chocolate milk (protein and carbohydrate) with isocaloric carbohydrate and placebo supplements in 10 cyclists.

Chemical Composition of Human Biology. Articles in the Biological Literacy series are fun explorations of how the human body works. See below for a complete listing of articles in the series. An ugly bag of mostly water. Let’s go a little deeper than that, though. Off to the chemist Suppose you wanted to make a person from raw elements. If you had a ray gun that could reduce a human being to elements, you’d have a whole lot of hydrogen and oxygen from all the water — approximately ten gallons worth — plus a bunch of carbon and nitrogen. “Everything else” is aluminum, boron, chromium, cobalt, copper, fluorine, manganese, molydenum, selenium, silicon, tin, vanadium, and zinc. But organized how? The plumbing All that water needs a bunch of pipes. This fascinating trivia about chemistry helps in understanding the tissue structures of our bodies.

But wait, there’s more (pipes) In fact, the circulatory system accounts for only about two thirds of the fluid-carrying tubes in the human body. Up your nose with a rubber hose Notes. Biomolecules (Updated) BioGems. An animation that explains how a bean gets digested. [VIDEO] Amino acids: MedlinePlus Medical Encyclopedia. Amino acids are organic compounds that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down foodGrowRepair body tissuePerform many other body functions Amino acids can also be used as a source of energy by the body.

Amino acids are classified into three groups: Essential amino acidsNonessential amino acidsConditional amino acids Essential amino acids Essential amino acids cannot be made by the body. Nonessential amino acids "Nonessential" means that our bodies produce an amino acid, even if we don't get it from the food we eat.They include: alanine, asparagine, aspartic acid, and glutamic acid. Conditional amino acids Conditional amino acids are usually not essential, except in times of illness and stress.They include: arginine, cysteine, glutamine, tyrosine, glycine, ornithine, proline, and serine.

A New Way of Looking at Proteins, Fats and Carbohydrates. Topics Discussion Introduction Most traditional discussions of macronutrients - carbohydrates, fats, proteins - revolve around the issue of quantity, either as the gram amount of these molecules necessary per day, or as the percentage of the diet that they should each contribute. While this is an important issue to consider, when it comes to these essential nutrients, quantity should not be the only concern.

These three classes of macronutrients are complex groups, each of which contains a variety of components. You can eat the same quantity of protein, carbohydrate and fat, but deliver very different nutriture to your body depending on the sources of these molecules. Following is an overview of macronutrients that will explore this topic, so you can get a clear picture of how the macronutrients in the World's Healthiest Foods promote health and wellness.
