Question

What are the different types of proteins their health benefits the possible risks of protein consumption?

Answer 1

PROTEINS

Proteins are the most abundant organkic molecules of the living system.they constitute about 50 percent of the cellular dry weight.proteins form the fundamental basis of structure and functions of life.Protein perform a great variety of specialised and essential functions in the living cells .

Different types of proteins:

proteins can be classified in several ways,

A.Functional classification of proteins

1. Structural protein: keratin of hair
2. catalytic proteins: hexokinase, pepsin
3. Transport protein : hemoglobin,serum albumin
4. hormonal protein: insulin,growth hormone
5. Contractile protein :actin, myosin
6. Storage protein : ovalbumin, glutein
7. Genetic protein :nucleoproteins
8. Defense protein: snake venom,immunoglobulins

B CLASSIFICATION BASED ON CHEMICAL NATURE AND SOLUABILITY

1. Simple proteins :they are composed of amino acid residues:eg:albumins,globulins,glutellins
2. conjugated proteins:these proteins contain amino acid residues and a non protein moiety known as proesthetic group;eg:glycoproteins,lipoproteins
3. Derived protein: the are degraded products of simple and conjugated proteins;eg:peptones,proteoses,coagulated proteins

HEALTH BENEFITS OF PROTEIN

Consumption of protein reduces appetite and hunger levels ,boost metabolism and there will be an increasein fat burning.proteins play a major role on tissue repair and maintenance. Consumption of proteins also reduces blood pressure

RISK OF PROTEIN CONSUMPTION

Consumption will cause harmful effect on the body.Finally results in ketosis. ketosis is the metabolic state characterised by elevated levels of ketone bodies.

In cases of atheletes who consume more protein powder would face sereious health issues in future.Protein pwder may add sugar and calorie.New risk that has been reported is the presence of heavy metals.
