Answer:
Because of the diverse methods of classification, consumers can often be confused when their doctor calls a drug an ACE inhibitor, their pharmacist calls it an antihypertensive, and they read online that it is a vasoconstrictor. Ultimately, all of these terms can be used to describe the same drug used for the same purpose.
Explanation:
A drug class is a term used to describe medications that are grouped together because of their similarity. There are three dominant methods of classifying these groups:1
By their mechanism of action, meaning the specific biochemical reaction that occurs when you take a drug
By their physiologic effect, meaning the specific way in which the body responds to a drug
By their chemical structure
Based on these diverse classification methods, some drugs may be grouped together under one system but not another. In other cases, a drug may have multiple uses or actions (such as the drug fin a steride, which is used to treat an enlarged prostate or to regrow hair) and may be included in multiple drug classes within a single classification system.
This doesn't even take into account the drugs that are used off-label for reasons other than what they were approved. A prime example is levo thyroxine which is approved to treat hypothyroidism (low thyroid function) but is often used off-label to treat depression
Essential nutrients includes proteins
It is well established that women generally have a higher percentage of body fat than men. A healthy range of body fat for women is 20-25%, and a healthy range of body fat for men is 10-15% (Robergs and Roberts, 1997). A body fat percentage over 20% for men or 30% for women is considered an indication of obesity. Body fat distribution varies among individuals and is a determinant of cardiovascular risk. Some people carry more of their body fat in and around the abdominal area. This type of fat deposition is called android, or apple body type and is most characteristic among males. The android body type is associated with a higher risk for cardiovascular disease. The body type most common among females is the gynoid, or pear body type. This body type is characterized by fat stores in the hip and thigh region (Robergs & Roberts, 1997). The scientific explanations for the dramatic difference in body fat distribution between men and women are largely unknown, although differences in hormones, hormone receptors, and enzyme concentrations play a contributing role. These possible mechanisms are discussed later in the section on epinephrine and lipolysis.
Heterotrophs
A major difference between autotrophs and heterotrophs is that the former are able to make their own food by photosynthesis whereas the latter cannot. Photosynthesis is a process that involves making glucose (a sugar) and oxygen from water and carbon dioxide using energy from sunlight. Autotrophs are able to manufacture energy from the sun, but heterotrophs must rely on other organisms for energy.
