Lens Proteinleri ve Fizyolojisi

Vücudumuzda bulunan bazı doku ve organlar dışında genel itibari ile beslenmedamar yolu ile olur. Fenestralı kılcal damarlar doku içerisine yayılarakdokunun ihtiyaç duyduğu oksijeni eritrositler, besin maddelerini de kanın serumkısmı ile taşır. Doku ihtiyacı olan metabolitleri aldıktan sonra artıklarınıda yine fenestralı kılcal damarlar ve lenf damaları sayesinde geri verir. Lensvücutta kan dolaşımının aktif olarak bulunmadığı ve canlılığını koruyan nadiryapılardan bir tanesidir. Beslenmesini ve artık boşaltımını aköz hümörebağımlı olarak gerçekleştirir. Lensin metabolizması bu yüzden özelleşmiş birdöngüye sahiptir. Vücuttaki tüm organ ve dokuların temel yapı taşı proteindir.Lens vücutta hacim başına en fazla protein olan dokulardan biridir. İçeriğindekiyüksek protein miktarı lensin ihtiyaç duyduğu yüksek kırıcılık indeksineve refraktif indeksin oluşmasını sağlar. Aynı zamanda lensin saydamlığınınkorunmasında da lens proteinleri önemli görevler üstlenir. Bununla birliktelens hücrelerinin birbiri ile madde alışverişi sağlayabilmesi için de fonksiyonlargörür. Lens hücreleri içerisindeki proteinler ise hücre şeklinin korunmasındagörev yaparlar.

Lens Proteins and Physiology

Except for some of the tissues and organs found in our body, nutrition generally takes place via the vein. Fenestral capillary vessels spread through the tissue to touch the needy oxygen erythrocytes, and the nutrients are carried by the blood serum part. Once the tissue has taken up the metabolites it needs, it also restores its debris through its fenestral capillaries and lymph vessels. The lens is a rare tissue of the body that does not have an active blood circulation and protects its vitality. It performs feeding and residual discharge dependent on aqueous humor. The metabolism of the lens thus has a specialized loop. The basic building block of all the organs and tissues in the body is protein. The lens is one of the tissues with the highest protein per volume in the body. The high amount of protein in it provides the refractive index and refractive index required by the lens. At the same time, lens proteins play an important role in preserving the transparency of the lens. However, it also functions to allow the lens cells to exchange materials with each other. The proteins in the lens cells function in protecting the cell shape.
