Importance Of Fish Biochemistry

ABSTRACK

Biochemistry is the role of many molecule in chemistry reaction and processing in live creature. Fishery Biochemistry is the role of many molecule in chemistry reaction and processing in all of fishery. It is really important to study because we can know the contain in fishery which benefit to our body. Fishery Biochemistry discusses protein analysis. The methods used in Fishery Biochemistry protein analysis are material weighed 0,5 grams then boil to The Kjedahl 100 ml, add about 1 gram of a mixture of selenium and concentrated H2SO4 10ml, and then homogenized. Destruction on a fume hood until pure, allowing to cool,then dumped in to 100 ml volumetric flask with distilled water while rinsing. Allowing to cool and added water until

One of the live creature is fishery. So fishery biochemistry is the role of many molecule in chemistry reaction and processing in all of fishery.

Fish composed of fresh water fish and salt water fish. Both are food sources which very important to growth of the body. Fish contain fat 1-20 % which very easy to digested and immediately can use for body tissues. Fish also contain carbohydrate, vitamin and water but less than 5%. Fish have a lot of protein up to 18% that is essential amino acids which not damage while time of cooking. The research showed that fish contain high quality of protein. Because of that need method to calculate the protein levels. Calculate the protein levels use Kjeldahl method.

DISCUSSION

2.1 DEFINITION:

Fishery biochemistry is the role of many molecule in chemistry reaction and processing in all of fishery. One of the sample is protein. Protein of fish, contain high quality protein. Protein on fish formed by amino acids which need for body growth. Protein of fish easily digested and absorbed. Amino acids which contain enough much and variation appropriate to body needed. The researcher find that amino acids are contain on food sources of an animal appropriate with human body tissue

2.4 METHOD OF EXPERIMENT Methods of experiment by Sudarmadji,.et al (1997). Working procedures as follows:

1. Materials weighed as much as 0,5 grams then boil to the kjeldahl flask 100 ml

2. Added about 1 gram of a mixture of selenium and concentrated H2SO4 10 ml and then homogenized

3. Destruction in a fume hood until pure. Allowing materials to cool, then dumped into a 100 ml volumetric flask with distilled water while rinsing

4. Allowed to cool and then add distilled water until calibration mark. Prepared reservoir consisting of 10 ml 2% H2BO3 and 4 drops of indicator solution in 100 ml Erlenmeyer.

5. Pipette 5 ml of 30% NaOH and 100 ml of distilled water, distilled until the reservoir volume of approximately 50 ml. Rinsed with distilled water distiller end then accommodated together its contents.

6. Titrated with a solution 0.02 N of HCl and H2SO4,calculating the protein content is performed as follows: % protein levels =
